While trying to open or place an anvil with the mods Easy Anvils & Apotheosis with the Enchantment Module is disabled it causes the game to crash, I have tested this multiple times in both old and new worlds and re-enabling the Enchant Module.

This is an issue with whatever compat code easy anvils has for apoth, as it seems like they are unconditionally reaching into ench module code even if it is disabled.
